glu GLU is the OpenGL Utility Library. This is a set of functions to create texture bitmaps from a base image, map coordinates between screen and object space, …

glut GLUT is the OpenGL Utility Toolkit, a window system independent toolkit for writing OpenGL programs Generic windows interface Provides user interaction functionsM

Others GLX 1.3 is used on Unix OpenGL implementation to manage interaction with the X Window System and to encode OpenGL onto the X protocol stream for remote rendering. MesaMesa is a 3-D graphics library with an API which is very similar to that of OpenGL.
